Anybody who witnessed the instant classic that Jo-Wilfried Tsonga and Milos Raonic played on Court 1 today needs to go think about putting an icepack on their shoulder. Have you ever heard of second-hand serving? It’s sort of like second-hand smoking but it hurts even more.

Here’s 10 quick thoughts on another wild and woolly day of Olympic tennis:

1. An Olympic Classic

It would be easy to throw a bunch of stats about Jo-Wilfried Tsonga’s 6-3, 3-6, 25-23 victory over Milos Raonic today: Longest Olympic set: check. Longest three-set Olympic match: check. But what those stats don’t tell you about is how Tsonga pulled off that match point after falling down behind the baseline. What an exciting finish to a match that certainly didn’t need the finish to be considered an epic.

Sad for Raonic, who played his heart out, and will certainly be rewarded in the future for the experience, but W-O-W for Tsonga, who continues to be one of the most dynamic and captivating players of this current era. Where Jo-Willy goes, drama, athleticism, and lightheartedness are sure to follow—what’s not to like about that?

2. Venus!

Venus Williams, with her shellacking of Aleksandra Wozniack of Canada on Tuesday, is into the last 16, and announcing herself as a potential threat to win—yes, you are reading me correctly—Olympic gold.

She’ll face a very stern test in German Angelique Kerber on Court 2 tomorrow, but the way that Venus is looking right now, she’s got a shot to pull another big upset. Either way, it’s fantastic to see the five-time Wimbledon champion (in singles and doubles) asserting herself on the grass like we all knew she could.

3. Bryan Brothers into Quarters

Mike and Bob Bryan took out Nikolay Davydenko and Mikhail Youzhny in two tense sets today to reach the quarterfinals. Tomorrow they can enjoy a day off and do some scouting of the Roger Federer/Stan Wawrinka vs. Jonathan Erlich and Andy Ram match which will be 3rd up on Court 18.

The Bryans lost a heartbreaker to Federer and Wawrinka at the 2008 Games in Beijing, but they will likely have to find a way past them if they want to keep their quest for gold alive.

4. Kim Clijsters: Head of the Class

Kim Clijsters is having a great time at Wimbledon, likening the Games to a school trip. "You kind of feel like you are going on a school trip, when we took the train and we were all dressed the same and had our backpacks," Games debutante Clijsters said. "It was fun and it was exciting, having been on tour for 15 years, to have a new experience." Clijsters will face Ana Ivanovic for a spot in the quarterfinals tomorrow.

5. Mixed Dubs Seeds, Draws Announced

The Seeding and draw for the Mixed Doubles portion of Olympic tennis was announced today. My favorite pairing? Lleyton Hewitt and Sam Stosur, with Andy Murray and Laura Robson coming in a close second. If each can manage a first-round win, wouldn’t that be a classic Mixed Doubles quarterfinal?

6. Dubs Classic, To Be Continued...

The longest set of the day may be the one that didn’t finish yet. Tomas Berdych and Radek Stepanek are currently deadlocked at 18 games apiece in the third set with the Brazilian pairing of Marcelo Melo and Bruno Soares. The match was called on account of darkness, after three-hours, forty-five minutes of knock-down, drag-out dubs. They will resume on Court 16 at 2 PM London time tomorrow.

7. Looking at the Last 16

Here are your men’s and women’s singles round of 16 match-ups:

Men: Federer-Istomin, Isner-Tipsarevic, Ferrer-Nishikori, Simon-Del Potro, Darcis-Almagro, Baghdatis-Murray, Tsonga-Lopez, Hewitt-Djokovic.

Women: Azarenka-Petrova, Venus Williams-Kerber, Serena Williams-Zvonareva, Hantuchova-Wozniacki, Clijsters-Ivanovic, Lisicki-Sharapova, Kvitova-Pennetta, Kirilenko-Goerges.

8. Rusty, but Not Over the Hill

Lleyton Hewitt, 31, is the oldest and lowest-ranked player (159) remaining in the men’s singles draw. But Steve Darcis (who?), 28 and ranked 75 is the guy nobody expected to be hanging around.

Venus Williams, at 32, is the oldest singles player to have reached the last 16.

9. 30-Something Watch

Four men and four women have made the last 16 in singles:

Men: Federer (30), Ferrer (30), Lopez (30), Hewitt (31)
Women: Venus (32), Serena (30), Petrova (30), Pennetta (30)
